Rolls RA2100b Power 2U Rack Mount 2 x 100W at 4 Ohms / 200W at 7

The Rolls RA2100b is an ideal installation amplifier for small to medium sized applications. The unit is built solid and housed in a painted steel chassis. It also includes special high performance transformers and a fused power line. The MOSFET output stage is fault protected which allows the R2100b to forgive momentary output shorts. It is design... moreed to drive 4 or 8 Ohm speakers, 25V speakers (individual channels) or 70V speakers (in bridged mode). CAUTION: The 2100b is convection cooled. Adequate ventilation room for the heat sink fins on the rear panel must be provided for.Features100W RMS per output (4 ohm)85W RMS per output (8 ohm)200W RMS into 70V (8 ohm)1/4" and RCA inputsFault-protected output stageSpecificationsPower Output, Stereo:100 Watts RMS/ch. 4Ohms85 Watts RMS/ch. 8 OhmsBridged: 200 Watts into 70 Volt or 8 OhmsMinimum Load Impedance: 4 Ohms (8 Ohms bridged)Sensitivity:95 dB A WeightedPower Bandwidth: 70 - 30 kHz +/- 3 dBDamping Factor: >150Slew Rate: 100 V/micro SecondPhase Shift:< 10°, 20 Hz - 20 kHzInput Impedance: 10 KOhms balancedPower: 120 VAC 60 Hz 2.5A, 230 VAC 50 HzDimensions: 19" x 3.5" x 7.5" (48 x 9 x 19 cm)Weight: 12 lbs.

The Rolls RA2100B is a stereo 100W/channel RMS power amplifier in a standard 2 rack space format. It is intended for professional audio and distributed musical applications. The unit features 100 Watts per channel RMS into four ohms, 85 Watts per channel into eight ohms and for the contractor - 70 Volts / eight ohms. The unit also features Moseft d... morerivers in a voltage and current gain circuit and a one-second input turn-on delay. The RA2100b will drive 25 Volt speaker lines directly from each channel, or 70 Volt lines bridged.
